CARDlNG-ENGINE.

SPECIFICATION forming part of Letters Patent No. 631 ,022, dated August 15, 1899.

Application filed March 15, 1898. Serial No. 673,912. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS R. MARSDEN, manager, a subject of the Queen of the United Kingdom of Great Britain and Ireland, and a resident of Bank View, Derker, Oldham, in the county of Lancaster, England, have invented certain new and useful Improvements in Oarding-Engines, of which the followingis a specification.

This invention relates to carding-engines, and relates more particularly to the driving of the doffers of such machines.

In consequence of the high speed at which carding-engines are now worked the delivery of web or sliver by the dofier of a cardin g-engine now takes place at a speed so great that, except by an attendant of more than ordinary dexterity, the piecing or passing of the sliver into the bite of the calender-rollers of a carding-engine after the sliver has broken down is not elfected quickly enough to avoid an accumulation of web or sliver beneath the doffing-comb, which is both objectionable and wasteful. To remove these and other objections, cardingengines have been provided with apparatus by means of which the attendant in charge of a carding-engine can reduce the speed of the doifer when piecing is to be effected and by that means reduce the speed at which the web or sliver is delivered by the doffer and so obtain more time for the piecing of broken slivers. It is the duty of attendants making use of such apparatus to set the dotfers at work at full speed again immediately after piecing has been accomplished; but careless or negligent attendants often omit to do so, and the doffers are allowed to continue Workin g at the slow speed, so that not only is the production of sliver reduced, but inferior work is done in consequence of some parts of the carding-engine being on their full speed while other parts are on the slow speed.

The object of my invention is the provision of arrangements of mechanism for the purpose of enabling the doflt'ers of carding-engines to be made to revolve at less than their full working speed when the webs or slivers, having broken down, require to be pieced and preventing the doffer's from being allowed to continue working at the slow speed by the mistake or neglect of the attendants in charge of such carding-engines after the piecing of the slivers has been accomplished or after such doiters have continued to revolve slowly for a sufficient length of time to allow of the piecing being done by ordinary attendants, thus insuring the prompt restoration of the dofiers to their full speed.

In the accompanying drawings, in all the figures of which the same letters and numerals of reference are employed to indicate corresponding parts, Figure 1 is a side elevation of so much of a carding-engine with one form of my invention applied to it as is requisite for the illustration of my invention. Fig. 2 is an end elevation, partly in vertical section, of a portion of that which is shown in Fig. 1. Fig. 3 is a plan of a portion of that which is shown in Fig. 1, one of the wheels shown being only indicated in part, so that parts below it may be clearly shown. Fig. 4 is a side elevation upon a larger scale than Fig. 1, showing the parts which are employed in accordance with my invention in the arrangement illustrated by Figs. 1, 2, and 3. Fig. 5 is a plan of part of that which is shown in Fig. 4:. Fig. 6 is an end elevation of a part of that which is shown in Fig. 4. Figs. 7 and 8 are respectively a side elevation at right angles to and a side elevation in the direction of the length of the carding-engine of a weighted lever shown but not capable of being fully illustrated in Figs. '1, 3, 4, and 6. Fig. 9 is a plan of a bracket shown but incapable of being fully illustrated in Figs. 1, 3, 4L, and 6. Figs. 10 and '11 are vertical sections through some of the toothed wheels and pulleys employed in the arrangement illustrated and the parts on which theyare supported, but with some parts shown in side elevation, so as to be clearer. Fig. 12 is a section, taken on the plane indicated by the line A A of Fig. 4:, through a pulley employed in the arrangement illustrated in Fig. 1 and the parts by which it is supported, but showing external views of some parts and with a part shown slightly out of position, so as to be clearer.

The doifer of the carding-engine, of which part is illustrated in Fig. 1, is arranged to bedriven by a belt a, arranged to receive motion from a pulley upon the axle of the takerin roller of the carding-engine and impart mot-ion to a pulley b, which is mounted upon a stud b, secured in a drop-lever c, and is furnished with a pinion b fast upon it and gearing into a toothed wheel d. The wheel d is mounted upon a stud e, secured in the drop-lever 0. To the boss of the wheel cl are secured the wheels f and h. The wheel f gears into a toothed wheel g, fast upon the axle of the doffer. The drop-lever c is arranged to be capable of being turned about a stud secured in the side frame 19 of the carding-engine. When is allowed to remain in a state of rest.

the drop-lever c is in its highest position, the Wheelf will be in gear with the wheel g. Then the drop-lever c is in its lowest position, the wheel h will be in gear with a wheel 2'. hen the drop-lever c is in the middle position, the Wheels f and h are both out of. gear with the wheels they at times gear with and the doifer The hand-lever c is connected to the drop-levers by means of the link 0. The catch 0 which is mounted on the hand-lever 0, determines the highest and middle positions of the droplever c. The engagement of the wheels h and 6 determines the lowest position of the drop-lever c. The weight of the parts mounted on the drop-lever 0 tends to move it downward and at the same time move the lever c in the direction indicated by the arrow D. \Vhen the drop-lever c is moved to bring the pinion f out of gear with the toothed wheel g, the toothed wheel h is brought into gear with a toothed wheel 1', formed with a pulleyj and a'bevel-wheel it and capable of being revolved upon a stud m, secured in the lower arm of a bell-crank lever 02, capable of being oscillated upon a stud 0, secured in a bracket 0, mounted fast upon the side frame 19 of the carding-engine. The upper end of the bellcrauk lever 71 is provided with a stud, upon which is mounted a pinion y, formed with a sleeve fast upon which is mounted a pulley 0:. Around the pulley a; and the pulleyj is passed a band '20, which in Figs. 2 and 3 is only indicated in part in order that other parts may be better shown. The pinion yis so placed that it may be brought into gear with the toothed wheel 9 by the bell-crank lever n being oscillated in the direction indicated by the arrow 0. hen the drop-lever c is low- .ered to bring the pinion f out of gear with the toothed wheel g and the toothed wheel h is brought into gear with the toothed wheel 7;,

- the drop-lever c and the parts carried byand connected to it bear upon the toothed wheel '5 and the lower arm of the bell-crank lever n, and so cause the bell-crank lever n to oscillate in the direction indicated by the arrow 0, so that the pinion g is brought into gear with the toothed wheel g. The pulleyj being smaller than the pulleyx and the wheel y being smaller than the wheelfithe bringing of the pinion y into gear with the toothed wheel g will cause the doffer of the cardingengine to revolve at the requisite slow speed.

A spring 2 is connected at one end to a stud securedin the bell-crank lever n and at the other end to a stud in a bracket upon the side 'framep. The spring 2 and the weight of the ed fast upon a shaft 1", which at one end iscapable of being revolved and slightly oscillated in a bracket n, secured to the bellcrank lever n, and at the other end is capable of being revolved in bearings provided in a. yoke s,capable of being oscillated upon a stud 's', secured in a bracket 8 mounted fast upon the side frame 19. The bracket n n is in two parts, as shown in Fig. 5, one, 01, formed with a shank or spindle (shown in dotted outline in Fig. 5) capable of turning in the other, at, which is provided with a screw 01*, entering a groove formed around the said shank and serving to retain the said part 'n* in position while permitting its oscillation. A worm tis mounted fast upon the shaft 0". The worm tis made to gear into a worm-wheel a, capable of being revolved upon the stud s. The worm-wheel u is provided with a sleeve 10, upon which is formed an arm 102, in which is secured a projecting stud u which if the worm-wheel u be revolved will comeinto contact with and turn a weighted tumbler-lever n, which is capable of being revolved upon the stud s and is furnished with a projecting finger 12'', which at times is capable of lifting the drop-lever c from its lowest to its highest position. The tumbler-lever and the sleeve u are kept in place lengthwise of the stud s by a collar 41*, (see Fig. 6,) which is placed on the said stud and secured bya nut thereon. WVhen the drop-levercisin its lowest position and the tumbler-leverohas been turned by therevolution of the worm-wheel it around the stud s in the direction indicated by the arrow B until the weight 12 upon the tumblerlever a: arrives above and is carried over the stud s' and tumbles over, the tumbler-lever 0 causes the project-ing finger o to raise the drop-lever c and bring the wheel f into gear with the wheel g and allows the catch a to drop into position to hold the Wheelfin gear with the wheel g. When the drop-lever c is released to disengage the wheel f from the wheel g and engage the toothed wheel h with the wheel 1' and the pinion y with the toothed wheel gfor the purpose of driving the dofier at a slow speed, the toothed wheels h i, bevel- Wheels 76 q, shaft 1-, worm t, worm-wheel to, arm 1L2, projecting stud "a and weighted tumbler-lever '11 will after a certain time, dependin g upon the speed at which the worm-wheelu, is caused to revolve,raise the drop-lever c,so as to reengage the wheel f with the wheel g,when

ously be limited to any required extent by the gearing employed being arranged to turn the projecting finger n at a suitable speed.

when it is necessary to piece up the sliver or web from the doffer to the calenders, the attendant lifts the catch 0 which permits the drop-lever c to change the driving of the doffer from the full speed to the slow speed to enable the attendant to piece the end. .Vhile this is being done, the tumbler-lever v is being brought into position to lift the droplever c. The lifting of the drop-lever c by the tumbler-lever t will change the driving of the doffer from slow speed to full speed. When the doffer is running at the full speed, the slow-motion parts are at rest.
